1 Claim. 1

This invention relates to sidingfor building construction and moreparticularly a corner construction for insulating sectional coveringmaterial therefor.

Exterior siding in the form of asphalt impregnated insulating boardhaving various exterior simulated appearances such as shingle, brick orstone is commonly employed to provide an exterior insulating andprotecting sheathing for buildings, such as dwellings and the like. Suchmaterial usually is supplied in relatively rigid panels of standarddimensions and having interlocking edge formations, for example such asshiplap, in order to facilitate installation with tight seams. Wheresuch material is used, difficulty is had in providing a cornerconstruction of a satisfactory nature, and the usual practice is toprovide an overlapping angle piece at the corners which is applied,after the adjacent sides have been covered up to the corners. such anglepieces rarely match the simulated appearance and spoil the overalleffect, and where a shingle construction is employed, fail to make atight joint over the slight saw tooth shingle surface. Further, theoverlap is wasted insofar as effectiveness is concerned.

The present invention is directed to a corner construction in which thecorner angle piece may i be laid flush with the siding without overlap,or flush with and act as an extension of a shingle or brick simulatedsiding whereby the appearance and overall effect of a continuous shingleor brick surface from corner to corner is provided.

Accordingly, it is an object of the presentinvention to provide a cornerelement or angle piece, which may in effect interlock with and form anatural extension of the side covering.

Another object of the invention is to provide a corner construction inwhich the corner element cooperates with both adjoining sides withsuitable interlocking edges in all respects similar to the interlockingsiding edges.

A further object of the invention is to provide a siding constructionwhich shall be economical in cost, eliminate overlap, easy to installand provide with the remaining siding a uniform overall effect as wellas a weather-tight enclosure.

The above and other novel features of the invention will appear morefully hereinafter from the following detailed description when taken inconjunction with the accompanying drawings. It is expressly understoodthat the drawings are employed for purposes of illustration only and arenot designed as a definition of the limits of 2 the invention, referencebeing had for this purpose to the appended claims.

In the drawings, wherein like reference characters indicate like parts:7

Figure 1 is a perspective fragmentary view of a corner simulatingshingles;

Figure 2 is a section taken on the line 2-2 of Figure 1;

Figure 3 is a section taken on the line 3-3 of Figure l;

Figure 4 is a perspective view of a corner section; and

Figure 5 is a section taken on the line 5-5 of Figure 1.

Referring to Figure 1, there will be seen the side wall surface ofahouse or other building 20 composed of clapboards 22 or other siding,to which has been applied insulating sections 24, 26, 28, 30 and 32,simulating shingles or the like. Each section is preferably rectangularand is of standard dimensions, except-short sections such as 24 may beutilized to break the vertical joints, provided with an edge suitablyshaped to interlock with the adjoining sections to the right or left andto provide a shingle-like overlap at top and bottom. In the arrangementshown, a shiplap construction is utilized.

Each standard fiat section may be composed of fibrous insulation boardsuch as Celotex or the like, the same being impregnated with asphalt torender the sameimpervious to moisture, and the exterior is covered-witha thick coating of crushed rock, ceramic granules, or the like 35, fusedupon a heavy asphalt surface at relatively high temperature. Each suchsection is provided along its edges with a tongue and groove, thesection 24 having along its upper edge a tongue 38, and groove orshoulder 40, and along its right hand end, a similar tongue 42, andshoulder groove 44. Along its lower edge is a reversely arranged tongue46 formed as a projection of the outer surface, there being a shouldergroove 48 therebehind. At its left hand edge is a similar .tongue50,'formed as a projection of-the outer surface, there being behind. Itwill be seen in the sectional view, Figure 3,

ashoulder groove 52 therethat the thick coating of crushed rock orceramic material is removed as at 54 for a distance equal to the lengthof the tongue '46 in order to permit the positioning of each course ofsections in overlapping relation upon one another in shinglelikefashion, the sections being slightly sloped or slanted relative to thesiding 20 in the manner of shingles.

As has previously been described, such construction, while formingexcellent protection for the side walls, presents difficulties atcorners, since the fibrous insulation board is prepared in massproduction and cannot be provided with edges suchas would be presentableand have shingle-like appearance if exposed at a corner, as is the casewith natural wood shingles.

In order to provide a suitable corner construction which may be massproduced, and which will be adaptable for use with the panel sectionsdescribed, a novel corner section or piece 5'6 is provided having flanks58 and 6t! angularly disposed, such flanks being constructed of the samematerial preferably as the siding material, and in the same manner, forexample insulating board suitably impregnated with asphalt, and coatedwith crushed rock, minerals, ceramics or the like bonded in asphalt.Such corner section, while fiat and before being formed to an angle, issuitably scored on its inner surface by providing during manufacture adeep 90 V out, such out being closed as at 62 upon forming tosubstantially a right angle. The cut may be coated with excess asphaltto seal the cut 62. Each flank is provided with a tongue 64 and shouldergroove 66 along one side edge, the tongue being an extension of theinner surface, and a shoulder groove 68 and tongue along the other sideedge, the tongue being an extension of the outer surface. The upperedges of both flanks are provided with an inside tongue 12 and outershoulder groove 14, and. the ceramic material commences at a distancedown from the shoulder 14, as at 18, equal to the width of the tongue.The lower edges of the flanks are provided with an outer tongue 80, andinner groove 82.

It will be seen from the description of the corner element that the sameis designed to interlock and fit with adjoining panel sections, thesections interfitting in such manner as to give th appearance of anormal abutment of adjoining natural Wood shingles. It will appear thatsuch corner elements, when arranged one over the other, will be inclinedfrom the vertical, and for a perfect fit, lower dimension A of eachflank will preferably be greater by the thickness of the tongue T thanthe dimension B at the top of the flank, and that preferably the upperand lower edges generally indicated at 83 and 84 will bear right anglesto the interlocking edge generally indicated as at 86.

From the foregoing, it will be observed that sections, if provided witha simulated shingle appearance, the sections having their ceramicsurfaces'scored suitably as at 88, to simulate abutting shingles, thenovel corner elements set forth will provide a flush continuation of theside sections to the corner, the appearance of which will besubstantially authentic, and afford even better protection against theweather than wood shingles butt joined as in the usual practice at thecorners.

Many and varied combinations may be designed to suit conditions, itbeing the main feature of the invention to provide a finished authenticcorner, which will give the utmost protection against weather and inwhich all joints will be interlocking, of, for example, the shiplaptype.

In covering a building with the shingle or brick simulated insulation,the present invention contemplates the positioning of the cornerelements upon the building initially, and thereafter placing the sidingsections working toward the center of the building. If the face of thebuilding be broken vertically as by a door or window, it may bedesirable to work from either side toward the center, so that thecorners may have an authentic appearance. However, where such is notpossible, the last section to be placed may be cut and provided with atongue and groove and fitted into the corner section. Any two adjacentpanel sections may be angularly bowed in position and then laid flat,the tongues and grooves thereby being extended into the adjacent panelsalready laid.

In some instances, a building wall may have a slight flare at thebottom. Where such is the case, the sections adjacent to the cornersections will necessarily be provided with inclined edges adjoining thecorner section, and pro vided with a suitable tongue and groove edges tointerfit with the corner section. If desired, corner sections havinggreater flank width at the bottom may be provided, but it will appearthat such construction does not lend itself so well to mass production.

It will appear from the foregoing, that there is provided by reason ofthe novel corner sections described, a novel panel siding constructionwhich may simulate wood, shingles, stone, brick, and the like, and whichmay extend from corner to corner with courses (if shingles) or theentire surface flush with the corner pieces. By such a construction, theoverall simulated appearance will not be disturbed by the corner pieces,such pieces actually being a continuation of the central intermediatesections. Thus, not only is the overall appearance improved, but thereis provided sealed protection unbroken at the corners.

While several modifications of the invention have been illustrated anddescribed, it is to be understood that the invention is not limitedthereto. As various changes in the construction and arrangement may bemade without departing from the spirit of the invention, as will beapparent to those skilled in the art, reference will be had to theappended claims for a definition of the limits of the invention.
